stava BEARING.

Application filed July 2,

To all whom it may concern:

Be it known that I, 1WILHELM HoL'roRP, a citizen of theGerinan Empire,residing at Hamburg, Germany, have invented certain new and usefulImprovements in'Beare ings, ci' which the following is: a specification.

My invention refers to bearings and more especially to an improveddevice for lubricating them.

The bearings oitx the kindv known havingl brasses, such vfor instance,as those used in connection with locomotive and ordinary car axles, areso constructed that the revolving pivot or axle journal bears against a.felt pad saturated with o-il, andv is thus lulnicated.` Now, as will vbeobvious, the drawback in this arrangement is that the pad is apt toquickly wear down and the lubricating means to get soiled, so that inshort, the krevolving member will not be lubricated as required, causingthe axles frequently to run hot.

The object of the present invention is to provide a device in which thethorough lubrication of the parts is secured along with an ample supplyof the lubricant, and this by the fact of the flow' of said lubricantbeing conducted by a. shoe, acting as wiper, disposed on the outsideolthe brasses and bearing up against the journal to a c ollector, whencethe lubricating means are caused to flow back into the main loilreceiver bythe rotation of the journal. The shoe is so constructed as toembrace a portion of the journal in a. manner which will enable saidshoe to wipe off-the oil from said journal after the oil has left thebrasses .so that itis led to the collector from where, by aid ofsuitable guide members arranged within and Without the shoe, it is againenabled to attain the journal which, by means of these guide members,again leads the oil on to additional oil guide mea-ns communicating withthe main oil receiver.

Owing to .reasons of a constructional nature, the main oil receivercannot in the case of car axles, be arranged above the bearings, so thatthe oil cannot be supplied to the bearings from above. In thisparticular case the co-llar 4fixed in the usual manner to the axlejournals of the car axles is made use of as an oil feeder, and this inthe way abovedescribed relatively to the journal. In this modifiedconstruction the collar likewise moves in a shoe having aper- 1920.Serial No. 393,746.

Referring to Figs. lto 4L and vof the drawings, b-rasses 2 aredisp'ofsed'jinv a -'traine 1, the mainbil receiver 3 being arranged ontop. Underneath the axle,-"i. e.' withinffthe lower'jportio'n of theiframe l, there provided a two part receptacle 4, 4, the two sections ofwhich are in communication with each other by means lof'af grooveor4b/oxf formed in a metal pad 7 lThis latter isi'furthermore providedwith two pairs of'ibores G, 62l serving tolestablish'coinniunicationbetween the Yface of thel metal padthat bearsVup against 'the axle andthegroova'r bores 5. The bores 6,6a terminate'in grooves 8', 8a

Fig. 6 .formed in said face and communicating with bores 9, 9a which fortheir part again terminate in ascending pipes 10, 10a communicating withthe Oil receiver 3. The receiver is connected to the brasses 2 in knownmanner by means of lubricating bores or nipples 11, 11a the orifices ofwhich are united by a groove 12. To either side of the brasses aredisposed pockets 13, 13a the edges 14, 14a of which, Fig. 3, are sodevised as to 'force the oil to iiow along the axle to the collectingand discharge points 15, l5,

f whence it may be taken along by the axle or shaft till the wiper edges16, 16 of the metal pad are reached.

By means of a spring 17 bearing against the bottom of an oil receptacle18 disposed within frame 1, both the containers 4, 4a as also the metalpad 7 are forced against the axlein order to secure the propercooperation of these parts. Besides said metal pad, there are alsoprovided in known manner felt pads 19 which are forced against the axleby means o't springs 20 and which coinmunicate with the receptacle 18last-mentioned.

In the modification illustrated in Figs. 7 to 9 the brasses 22 mountedon the journal 23 are disposed within the casing 21. A felt pad 27surrounded by a Sheet metal cover 26 and whose edges extend beyond theedges of the felt pad to form a lateral oil receiving channel or grooveis forced against journal 23 by springs 24 bearing up against theunderside of said casing and the bottom of the casing 21 constituting acombined collector and main oil container 25. A collar 28 f disposed onthejournal is embraced by a sideof the shoe adjacent to collar 28, and

terminating in grooves 32, 32a. These latter again communicatewith pipes33, 33a, which for their part discharge in grooves 34, 34@l formed byjournal 23, felt pad 29, and sheet metal cover 26.

1n the case of both forms. of construction there may be arranged belowthe journal or collar a small feed roller 35 (Figs. 5 to 9), arranged inthe one hand, to dip into the oil, and on the othermaking contact withthe rotating member by means of which it may be caused to revolve.

The manner of operation of the device applied to the bearing shown inFigs. 1 to 5 is as follows:

The lubricant flows from the main oil container3 through the nipples orbores 11 into the groove 12, where it spreads and is taken along by therotating members as far as the sharp edges 14 or 14a of the pockets 13or 13a- (according to the direction in which the said member revolves).The edges 14 and the containers 4, 4a, whence it flows into groove 5..ln consequence of the suction action exerted by the shaft, the oil isdrawn up through the apertures 6, 6a, conducted to the grooves 8, 8a,then forced through the bores 9, 9a, from where it returns in the mannerhereinbefore described through the ascending pipes 10, 10n into the mainoil container 3.

ln the case of the modication illustrated in Figs. '7 to 9 the manner ofoperation is as follows:

The oil contained in the main container 2 5 (the shoe extending into thesame for the height .of thel collar) is drawn up by the bores 31, 31aformed in the shoe 30 as the collar 28 turns in the clockwise direction,and then forced by the groove 32 into the pipe 33, whence it reaches thechannel 34 and the telt pad 27. rl`he journal is thoroughly lubricatedby the felt pad, mainly however by the oil contained in the channel 34,the said journal wiping the oil oil' again on the felt pad close to thechannel 34a, whence by overflowing across the sheet metal cover 26 itiinally attains the container 25.

@n the rotation being reversed, the oil Hows through bore 31a, alonggroove 32, through pipe 33n to channel 34a, and from here by means ofthe journal to channel 34. ln the event of the oil not reaching thelevel of the rotating member, or of the bores 6, 6a (Figs. 1, 4, 5, 6)or 31, 31a Figs. 7 to 9) being stopped up, it is supp ied to these partsby means of the small feed roller 35.

I' claim:
